Research project: Static and cyclic load compression tests under controlled climatic conditions

Matthew A PerrasSimon LoewKerry Leith We aim to advance the frontier of progressive rock failure combining laboratory data derived from new custom built creep testing machines (capable of regulating temperature, humidity, and mechanical load over at least 100 days) with measurements from existing field equipment. Initial testing will be focused on unique natural and man-made […]

MSc Martin Kradolfer: The role of ice filled cracks on rock slope stability – a laboratory study

Candidate: Martin Kradolfer Supervisors: Florian Amann, Kerry Leith Institution: ETH Zurich Activity: Beginning Fall 2017 Project Framework: Ice filled tension cracks are commonly observed in association with active or catastrophic rock slope failures located in potential permafrost regions of the Alps. Displacement or dislocation along cracks in many of these rock slopes has been observed to primarily occur […]
